    OK, I am giving it a try. According to the watch even though it had the Wave Ceptor function on all the time, it shows no signal received in the right lower corner. And it says the last update was on 6/19, but I am not even sure if this is this year.

    I will let you know if it receives the signal.

    I completely agree with your opinion that it's without excuse. As is the programing of our traffic lights so we spend almost all our time accelerating or braking when the government claims to be in favor of clean air. That's another thing that's unnecessarily stupid when 55 years ago our family could drive practically all the way across the city where I grew up and we'd see each traffic light turn green just in time so we didn't have to stop. We were back there in May and the lights in that city still worked that way, at least on the streets we traveled.

    Sometimes it makes me want to scream, but then I try to get back to a perspective that's better for my blood pressure. :D

    Nop... No WaveCeptor signal received.

    The only other thing I can think of is to make sure it's not near a compact fluorescent or LED light that's on between 02:00 and 05:00. The ballast can make enough noise that the signal can't be received. Also, try some different areas of the house. I've found specific locations in the house that reliably work and others that are spotty. Maybe try leaving it outdoors one night to rule out any interference in your house. It should definitely work outdoors if oriented to the west southwest from New England.

    Maine is talking about doing away with it *and* moving to the Atlantic Time Zone. That would be a disaster for us Southern Mainers, especially those of use who work out of state.

    Yeah, I just downloaded owner's manual for my watch and checked it's functions again. As far as I can remember, I have not seen the signal receiving indicator lit at any level for a long time. The diagram on the manual pointed by the red arrow is what I see all the time now. I do remember it was functioning a long time ago when I traveled to Midwest, but I did not check it on my more recent travels, so not sure if it is still functioning or it's now completely broken. Oh well, it's not a big deal. As I said, even without the Atomic Clock signal, it still keeps extremely good time without needing any adjustment.

    In my old hometown, there was a stretch of about 6 lights that were all synchronized. They had a bunch of accidents when the lights were synchronized. Too many people ran the first light on yellow and then sped up to try and catch the next several lights before they went yellow. It was fine if you hit it green. Then there was an accident where two people got killed. They shifted the lights all over so you never caught them all green.

    Random timing causes accidents too. People see cars waiting to cross the intersection and know the light could turn at any second so they speed up so they'll make the light if it does. They also speed up after waiting at many red lights to "make up time." The bottom line is that if you're trying to use traffic devices and signs to control human nature, you're going to fail.

    OK. I ran one test to see which clock is controlling the charging. I set the charge time to start at 17:55. The MID clock read 17:50 and I don't know what the multimedia clock was set to because there's no way to look at it that I know of. I did have the DST box checked for the test, so I presume it was 18:50. I connected the charging cable and charging began at 17:55. "Ok," I thought to myself, "the MID is controlling the charging." So I reset my charging schedule for departure at 04:50 and plugged the car in.

    Sure enough, the charging stopped at 03:45 with a full charge. This is unusual because charging has always ended within 10 - 15 minutes of the programmed departure time. In fact, I've occasionally had trouble with it not being ready at departure. I've never seen it finish over an hour early (except the last week or so), so something weird is going on but I'm not sure what or how to troubleshoot. I don't believe in coincidences, so I strongly suspect a DST issue.

    Why not set the charge schedule "start at" instead of "departure at". If you are using L1, just set the start time to be 6 hours 10 min earlier. Although my L1 always finishes 45min to 1 hour earlier than what the time remaining tells me.

    Two reasons:

    1. Now that I've observed the problem my mind cannot be at peace until I successfully troubleshoot the cause, and

    2. I use departure time because I'm trying to leave the battery at full charge for minimum time. If I set by start time I'm not sure what happens when you plug in after the scheduled start time. Does it start charging immediately, or does it wait for the next occurrence of the start time?

    When charging L1 from 0%, my MID displays 5:50 remaining until full charge.

    Humm, mine always displays 6:10 remaining to full charge. This has not changed entire time I have owned my car, but it is almost always finishes earlier.

    Interesting. I wonder if that guess is based on an actual measurement of Amps in? Maybe each L1 charger varies in output a little bit due to different voltages. For example, my service is close to 121V, so maybe that drives the L1 charger a little harder than someone who's service is 115V.

    Be lucky you can even press that lower right button. Mine is no longer functional, but I'm too cheap to get a new one until this one breaks completely.

    I haven't opened this model to see, but my older Casios (before the advent of WWV receivers in watches) had a screw inside that fine tuned the watch's timekeeping. I used to fiddle with those until I could keep it accurate within about a second per week. I didn't have a good way to adjust the screw finely enough to improve upon that.

    That is plausible explanation. However, my wall reading of voltage using Kill-a-watt meter is very similar to yours at 120.4V.

    Maybe just inherently variability in L1 output, or slightly different battery capacities.

    Mine without not being adjusted by the Wave Ceptor, is off less than a minute in ~6 mo when I have to manually change time according to DTS. So that would be at most 2.5 second/week? This is comparing to the time displayed on a computer or a smart phone. I am assuming they are as accurate as the atomic clock, aren't they?

    Depends on your definition of accurate. I start getting itchy if I can perceive a difference between the "ticks" I can hear when I tune in WWV and the changing seconds on my devices, but that's just a useless quirk on my part. In the days before WWV receivers I used to set my watch every 2 or 3 days by manually dialing the USNO or NIST.

    Yeah, I think I've had my Casio for longer than 10 years now, way before I bought my first smartphone. Internet did exist then but not sure if the time keeping on computers were accurate back then. Then again, I was never that obsessed about accuracy, like you. :D:D:D

    Interesting that you mentioned that. Since the switch to DST, mine has been finishing about an hour early even though the clocks are correct. I haven't played with start times because I prefer to use departure time so it starts charging before I get up in the morning and I don't have to remember to go plug it in at the right time in the afternoon. I guess it won't hurt to be done an hour early, but there's still something not quite right.

    .

    More specifically, the difference is due to a voltage difference which in turn affects the amperage. My line voltage is always spot on at 140V when I check it. [Correction: My L1 voltage is normally 120-130. Had a senior moment there. Or else it was a total brain fart. Sorry for the confusion.] My time to charge on L1 shows 5 hours and (I think) 40 minutes. I think at work it's 5:50 and that's 130V there. [Hmmm. I think I should check those times again. Memory might have failed me there.]
